Clarksville Weather
Clarksville's spot in the Northern Highland Rim of upper Middle Tennessee, 382 feet above sea level, brings us mild winters and hot, humid summers. In 2006 and 2007 Montgomery County faced a shortage of rain, as totals were below average. Totals were well below average every month in the first half of 2007 with the exception of January, when a half-inch more rain than the average was collected, said Tommy Williams, assistant superintendent for Clarksville's Wastewater Treatment Plant, where the city's official weather instruments are located.The total amount of rain accumulated in 2006-07, 45.28, was also significantly less than the annual average of 52.61. Most precipitation occurs during the winter months, with the least amount in the fall. Average rainfall is about 4 inches per month, but rainfall can deviate widely.
The first freeze usually arrives between Oct. 15 and 21, but in 2004 it didn't happen until the end of November. The last freeze usually occurs in the first week of April.
Williams indicated in an e-mail that Clarksville "had a very unusual spring of 2007."
"I talked to Ralph Troutman, with the National Weather Service, and he said that March's average temperature was the average of what April should have been," Williams said.
Clarksville's coldest day in 2006-07 was Jan. 31, when it was 11 degrees, and the warmest days were Aug. 10 and July 19, when it was 96 degrees, Troutman said. Clarksville's all-time high temperature was 112 degrees, recorded on Sept. 7, 1925, and the all-time low was -17 degrees, recorded Jan. 24, 1963.
July and August are usually Clarksville's hottest months of the year, averaging temperatures of 78 and 77 degrees, according to National Weather Service data from 1,591 months from 1854 to 1996. January is usually the coldest month, with an average minimum temperature of 34 degrees, National Weather Service data from 1961 to 1990 indicate.
December, on the other hand, saw a rise in temperature, as the average was 43.8 degrees, compared with an annual average of 39.2. "December of 2006 was over 4 degrees above normal. This is very high for a month period," Williams stated.
Twenty-two tornadoes have touched down in Montgomery County between 1950 and July 18, 2007, according to the National Weather Service. The most famous tornado came Jan. 22, 1999, when an F3 destroyed much of downtown Clarksville.
Clarksville usually gets a couple of snows each winter. The city's all-time record for snowfall was 12 inches on Jan. 6, 1910, according to National Weather Service reports.
